This change introduces the `action_args` crate which is something I feel
I keep writing in various repos now. It's original design is to make it
easier to pass args to built binaries. E.g.
```rust
use action_args;
use clap::Parser;
use runfiles::{rlocation, Runfiles};
#[command(version, about, long_about = None)]
struct ClapArgs {}
fn main() {
let args = {
let runfiles = Runfiles::create().unwrap();
let var = std::env::var("ARGS_FILE").unwrap();
let runfile = rlocation!(runfiles, var).unwrap();
let text = std::fs::read_to_string(runfile).unwrap();
let argv = action_args::parse_args(text);
ClapArgs::parse_from(std::env::args().take(1).chain(argv))
};
// ...
// ...
// ...
}
```
This utility will likely be unnecessary should
https://github.com/bazelbuild/bazel/issues/16076 ever be implemented.
